UNITED STATES PATENT OFFICE.

ALBERT E. HOLADAY, OF NAUGATUCK, CONNECTICUT, A SSIGNOR TO THE AMERICAN WBINGER COMPANY, OF WOONSOCKET, RHODE ISLAND, A CORPORATION OF RHODE ISLAND.

To all whom it may concern:

Be it known that .I, ALBERT E. HOLADAY, a citizen of the United States, residing at Naugatuck, in the county of New Haven and State of Connecticut,'have invented certain new and useful Improvements in- Pressure-Roll Releases for Clothes-Wringeraof which the following is a specification, refer-' ence being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in pressure roll release for clothes wringers and is an improvement on an application for pressure roll release for clothes wringers filed by John F. Hemenway, July 12, 1916, Serial No. 108,909, the

object being to provide a release which is exceedingly simple and cheap in construction and one which is' so constructed that the movably mounted top bar carrying the pressure screws which release the pressure, is

a connection therewith so that when the slidably mounted member is depressed, the ends of the resilient member will be drawn inwardly from under the keepers so as to release the top bar.

Another object of my invention is to provide a novel form of keeper-which is so constructed that when the resilient retaining member is drawn inwardly from under the same, the members carried by the retaining member will be caught by the keepers so as to limit the upward movement of the top bar in order to prevent the same from becoming detached from the wringer frame.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the accompanying drawings,

Figure 1, is aside elevation partly in section of a clothes wringer showing the ap- Specification of Letters latent.

Application filed July 26, 1916. Serial No. 111,402.

plication of my improved construction of pressure roll release thereto;

Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1;

Fig. 3 is a detail perspective view of a pair of keepers, resilient member, and operating'member showing the same separated;

Fig. 4 is adetail View of a slightly modified form of connection for the operating member and Fig. 5 is still another slightly modified 01m of a connection for the operating mem- Like numerals of reference refer to like parts in the several figuresof the drawing. In carrying out my invention I employa Wringer frame 1 which is provided-withthe usual slotted side bars 2 and 3 in which are mounted the bearings for the roller shafts carrying pressure rolls 4 and 5 which are preferably provided with meshing gears, not shown, inclosed by gear casings. The upper bearings for the upper pressure rolls carrying a shaft are provided with spring supports 6 on which are mounted coil pres sure springs 7 carrying plates 8 secured on the ends of a pressure bar 9, said plates being preferably provided with depending studs fitting within the upper portions of the coil spring 7 as clearly shown in'Fig. 1.

Slidably mounted within the slotted portions oftheside bars 2 and 3, is a top bar 10, which is provided with pressure screws 11 engaging the plates 8 of the pressure bar 9, so as to adjust the pressure on the pressure rolls.

In order to provide'means for holding the top bar 10 in a predetermined position withinthe wringer frame so that the pressure screws 11 carried thereby will exert the' proper pressure on the pressure screws through the medium of the plates 8, I provide each of the furcations of the bifurcated bars 2 and 3 with keepers 12 on its inner face. each of said keepers being formed .identically alike, and the description of one will be suflicient for all. Each keeper is provided with a horizontally disposed base portion 12' under which is adapted to extend antifriction rollers 13 carried by the end portions of a pin 14, secured in an eye 15, formed on each end of the resilient member 16-which is slidably mounted in guide members 17 secured to'the top bar '10 as clearly.

shown in Figs. 1 and 2, so as to prevent the 'top bar from moving vertically within the wringer frame.

5 The keepers 12 are provided with guideways for the rollers 13 which terminate in hooked portions 12 which are engaged by the antifriction rollers 13 of the resilient member 16 so as to limit the upward movement of the top bar after the,rollers 13 have been moved inwardly from under the horizontally disposed portions 12 of the keepers 12.

The resilient member 16 is provided with a centrally disposed bowed portion 18 having a boss 19 extending upwardly therefrom .which is provided with a substantially key hole shaped slot 20 adapted to receive the head 21 of an operating pin 22 which is '20 slidably mounted in a vertical bore 23 of the top bar 10, said spring being connected to the pin 22 before the same is secured in position within the guide members 17 and it I will be seen that by throwing the spring 25 obliquely in respect to the under side of the top bar, the head thereof can be forced through the enlarged circular opening of the key-hole shaped slot formed in the boss 19 soas to place the head in position-on the narrow portion of the slot in order to detachably connect the operating pin to the v resilient member.

In Fig. 4, I show a bowed resilient member or spring 24 having an opening through which the reduced lower end of an operating pin 25 is forced and headed in order to se cure the pin to the spring.

In Fig. 5, I show an operating pin 26, having a reduced portion provided with a 40 transverse bore, said reduced portion ex-' tending through an aperture formed in the bowed spring 27, and secured in position by 'a cotter pin 28 extending, through'the bore ofthe spring so as to detachably connect the operating pin to the spring.

In the operation of pressure release as herein shown and described, assumlng that the wrlnger is in the'positlon as shown 1n Fig. 1 with the pressure bar under pressure by the pressure screws carried by the top bar, when it is desired to release the pressure in case of a foreign object being drawn between the pressure rolls 4 and 5, by strik ing the head of the pin 22, the spring 18 will be forced downwardly so as to contract or draw inwardlytheends ofthe spring soas to draw the anti-friction rollers 13 from under the horizontally disposed portions 12 of the keepers 12 which allows the top bar 10 to move vertically in order to instantaneously release the pressure from the pres; sure rolls. As the antifriction rollers pass from under the horizontally disposed por-- tions 12.. of the keepers 12, the spring 18 expands so as to force the antifriction rollsu're means.

mounted therein, a movably mounted top ers into the guideways of the keepers into such a position that they are engaged by the hooks 12 which prevents the top bar from becoming detached from the wringer frame.

This is accomplished by giving the pin a quick blow which draws the ends of the spring inwardly a sufficient distance to allow the top bar to move upwardly, and as the impact on the pin is instantaneously released, the spring normally expands so as to cause the antifriction rollers to travel in the guideway of the keepers.

From the foregoing description, it will be seen that I have provided an exceedingly novel form of pressure release which can be readily attached to any of the well known forms of wringer now in use without changing the construction ofthe same in any way, as the releasing spring is so positioned that the top bar and the keepers on the side bars can be readily attached without. changing the construction.
